The rising threat of cyber attacks, especially distributed denial-of-service (DDoS), makes the IP Traceback problem very relevant to today’s Internet security. IP Traceback is one of the security problems associated with identifying the source of the attack packets. This work presents a novel approach to IP Traceback Deterministic Packet Marking (DPM). The proposed approach is scalable, simple ...

This paper discusses several of the SOC design issues pertaining to dynamic voltage and frequency scalable systems, and how these issues were resolved in the IBM PowerPC 405LP processor. We also introduce DPM, a novel architecture for policy-guided dynamic power management. We illustrate the utility of DPM by its ability to implement several classes of power management strategies and demonstrat...

A reliable description of dense gas–solid two-phase flows of Geldart A particles in gasfluidized beds at life-size scale is of great practical importance in process industries. The classical two-fluid model, based on the kinetic theory of granular flows (KTGF), provides a very promising theoretical framework for predicting large-scale gas–solid twophase flows. However, thus far the two fluid mo...

Background And Aim: Biliary atresia (BA) can be associated with ductal plate malformation (DPM) like changes in as high 40% of patients. It is variable prognosis, most the studies suggesting poor overall outcome. Aim isto study clinical and histological parameters biliary patients without DPM. Methods: Medical records diagnosed from January 2021 to September 2022 were analyzed. Histology every ...

A low cost, battery-operated, portable, real-time aerosol analyzer is not available for monitoring diesel particulate matter (DPM) concentrations in underground mines. This study summarizes a field evaluation conducted at an underground limestone mine to evaluate the potential of the TSI AM 510 portable photometer (equipped with a Dorr-Oliver cyclone and 1.0-mum impactor) to qualitatively track...
